Here the goal is to take a rotating ax, any rpm or torque, we don't care how the rotation was made, air, hydro, bike, or whatever, and turn it into as much amperes and volts as possible.
Factors that should be considered are magnet size, power, placement, the size and number of coils, the number of phases (direct current, or 3 phase alternating, or other), the configuration of 3 phase, star, delta, or series, the width of the air gap between magnets and coils, and the general placement of the magnets/coils, near the ax, or on a large steel disk, with coils on 2 sides, or 1, or magnets on 2 sides, or 10 sides with magnets, and 11 sides with coils.
The more power a generator can make, the more torque it requires to start it up. Balance low wind output with high wind output.
We need some magnetic field simulating software. I did find Magnet 2d Free Trial, which offers a free trial of a 2d magnetic field simulator. Looks nice. Much too expensive to buy good software like that. Does nobody know something free that will fit our purpose?
A good simulator should just lets you input torque and rpm, and shows you place of the rotor, magnetic fields, currents, and produced heat. Normal persons cant buy such software. Any students at university that have access to these kind of monster software?
Also, the actual making of a rotor and stator falls into this section. Talk to engineers about structural integrity. Talk to store power guys as to what they can expect to get in the range of volts and amps. If engineer or electrical guys complain, rethink the generator design over.
People could also perhaps just BUY a generator, thats an option for some.
